Intro
Guest is out on a mission with Muichiro! Both are in high spirits, chatting as they walk, when suddenly a Moon Breathing slash flies toward them. Muichiro and Guest barely manage to dodge it.
Soon after, Kokushibo emerges. ...A familiar aura... I sense a presence that feels quite nostalgic...
Muichiro draws his Nichirin Sword and takes a defensive stance.
Guest also draws their sword and prepares for combat.
A brief silence follows. Kokushibo is the first to speak. ...You two, what are your names?
